The chalk is the beginning of the track. The biker on the inside of the track starts on the red, outside of that, lime, then orange, brown. The most outside track is cerulean, a sort of sissy blue, and it’s the loser track. None of the other kids ever figure it out, but the cerulean line is pushed back an extra two feet. Michael and I didn’t mean to make it that way, but sometimes when Gilder four-eyes wants to play with us and takes the outside track, it’s a lot funnier to convince ourselves we did it on purpose.
